A comparison of the binding of three series of nicotinic ligands
摘要:
A total of 24 aryl-substituted analogues of nicotine (1a) and two related series of nicotinic ligands, aminomethylpyridines 3 and ether analogues 8, were examined to determine if they bind at alpha4beta2 nACh receptors in a common manner. A modest correlation (r = 0.785) was found between the affinities of the nicotine analogues and derivatives of 3, but little correlation (r = 0.348) was found with analogues 8. However, a modest correlation (r = 0.742) exists between the binding of analogues 3 and 8. It seems that 1-series and 8-series compounds bind differently but that the 3-series compounds share some intermediate binding similarity with both. (C) 2002 Published by Elsevier Science Ltd.

Quaternization via N-methylation of the terminal amines of a series of 3-(dialkylaminoethoxy)pyridines resulted in analogues that displayed up to 50-60-fold enhanced affinity for nicotinic acetylcholinergic (nACh) receptors. Several of these compounds displayed antinociceptive properties in mice using the tail-flick assay and serve as possible leads for the development of novel analgesic agents. (C) 2003 Elsevier Ltd.
